Grimm's Silas Weir Mitchell on How Monroe Has Evolved

IGN:
You probably know Silas Weir Mitchell from his roles in shows such as Prison Break, Burn Notice, My Name Is Earl, and many more. Most recently though, he's found a home starring in NBC's fantastical series Grimm. He portrays Monroe, a Blutbad – a creature similar to the Big Bad Wolf, who has changed his ways and is trying to lead a “normal” life. He often helps Detective Nick Burkhardt (played by Nick Giuntoli), a Grimm, despite the fact that they should be mortal enemies.
